Mounted in bearings such g as 23 in the upper platform of the carrier and ,in proximity' ofthe periphery thereof f are vertical` spindles 24 which `are rotated :in unison from the spurwheellS engaging the vgear wheels 24 whichv are fixedlyl coni nected with the/.respective spindles. 'These spindles are movable longitudinally for -adjustment purposes or yto compensate for wear, the take up for which is accomplished by thrust screws 23"y which extend lthrough the vbearing ends 232 provided therefor. In the lower of said carrier platforms'is a series of vertical -mandrels 25 corresponding in number and disposed to bein axial alinement with the spindles 24, that is to say, iny

pairs severally comprisedof an upper spindle land' alower mandrel. 'Such mandrels are desirably non-rotatable Ibut support spindles 27 which are rotated bythe spindles thereabove and through the services of the cans which 4are clamped therebetween. The mandrels are', however, arranged to besuccessively raised to effect such ycan-clamping function and then maintained in such condition'v while the seaming 'operations are being performedwhereupon the mandrels are successively receded to release the cans. These actions for engaging and disengaging `the cans) are attained .byprovid'ing-at t-he lower ends ofthe respective mandrels rollers 25 which travel upon a circular track having diametrically opposite portions .26

.and 26' varranged in different liorizontalv 'desirably are disposed to receive the supplied to the carrier and retain them 1n' positions to be clamped by the before de.

The top spindles' 24;' carry 2&3 which, as illustrated, are provided at the botto'm'with peripheral a ges 24? of diameters to'allow 'of v.their entering the' recesses The upper and lower of standards 193 located in the radialplanes of `Slidably seated in slots 194 upon the opposite sides ofeach of the stan'dards are'bars 3Q and 30 .which carry former-wheels 31 and 31` at their outerends lat their ,inner ends. tivo horizontal disposed in the disposed in planes and those which are upper plane' are adapted to track earn' element '33,while the others, traclr against a cam'element 33. Both of 'these elements 33 and' 33 are stationary and are fermcdupon a sleeve 332 which is rigid with the shaft 11. Said bars are individually connected by springs, such as 34, .withvsaid standards,

thereof. against the respective-cam elements or. the "sleeve, case may be. v 35 represents 'a feed-wheel connected with the carrier, so as to rotate therewith and is provided Witha series of pockets 35 which cans as they are scribed adischarge spout after the cans have clamping devices..

37 is an endless conveyer chain passing` about a driving sprocket wheel 38 upon the shaft 20 and thence about guide-wheels such as 38 'so as to lead from abench, not shown, through a transversely arranged trough 39, see Fig. 2, provided upon the machine frame and disposed at an elevation 'so that the top of the chain will be slightly hi gher than the top of the carrier platform 192. tpaced'atl suitable distances apart along said chain are linlrattachments 3T which serve to drag the cans '36' of the machine frame upon their lower ends' collars,

as the I been released lby 'such have'a portion of the chain' 'from the said bench to a reciprocating can feeder Whieh'transposes the bans, as C, one by one'fr'onithe chain to the carrier as the latter'ievolves in the progress of the work. .More particularly the 4feeder comprises a. bar 40.' mounted 'in fa guidefsupport 41 of the machine framesoas to be reciprocated in directions radially of the axis ofthe carrier 19 and at the end adjacent thereto it is provided ivith a'concavity 40 in 'which the cans are seated while being transferred from tl chain as aforesaid. Intermittent,l `ot`ion .is mparted to the feeder-bar by a leve 49, ful'- crumed at ltto an arm 41 41 andreceiving vibratory motion from suitable devices upon vthe shaft 20, such as by a stud 422 upon one ofthe lever arms project ling into a. cain-slbt s13of a drum 43 upon the said shaft; while the other arm of the lever is bifurcated, as Aat 423, to straddle a pin ltOzeXtending through the feeder-bar.

In ezqlaining` the operation of the invention I will, fpr ciearncss, designate the cir@ -cular Walls of the cans as ,the shells s. These shells are, previously to the operations herein contemplatech formel with marginal flanges as at f in Fig. '5. rI'he can vends c are each similarly formed with li peripheral flange g about the shouldcrv'h ofl a'r'lcprcsscd central portion le. Such shells with the end thereupon, as at A in Fig. 5', are new placed by an' attendant upon theI moving chain 3T which conveys them in such condition to the .feeding b ar Ll0 by which they are transferred .to the rotating carrier of the' machine. lThe work thus presented isreceive'd in the revolving-pockets 35 of the feed-wheel and carried thereby in the direction indicated by the arrows in Figs. I1` andr 3, the strokes of the feeding-bar being timed to insure each such pocket 4being thuscharged. As the carrier 19 rotates, the mandrels 25 are successively raised through the oice of the track 26-26 thereby elevating the canparts and bringing the' ends c which are uppermost. into position to receive the heads 244 of the upper spindles Zet and cause them. to forcibly cuter the depressions 7c of such ends. Vhen this ensues and through the rotation transmitted tov these spindles through the medium of the rotating spurwheel 1S acting upon the gcar-wheels 251i accelerated by the motion derived through the rot-ation of the carrier 19 causes the work to be clam-pcd between the several pairs of spin-v dles Q4 and 2T spinning at a high vclccity. As the' clamped cans are carried' about their orbital, the former-wheels 3l first act through the rolls 32 thereof being vcontrolled by thecam 33 to turn the flanges f'/ of the ends e over the e'dgc's of the shell. tlangcs j. as represented progressively in R and C of Fig. 5. -The continued action of these former-Wheels accomplishes the curling of the anges f and g to occupy therclativi of the support.

ifea

posit-ionsin which' theylare shown in D of I the view When the Workl of the former- Wheels Sl'ceases. The other former-Wheels 3l are thereupon caused by the controlling rolls 32 and theagency of the cam 33 to act to compact the folds vthus imparted by "the-other:former-Wheels and thereby com? plete the double-seaming operations.

The afore described actions ofthe machine in accomplishing the forming and compaetf ing of the can-seams are,'as will be apparent, while the mandrels are passing over the elevated portion 2G of the track and when. thel cans are in clamped condition. After this the mandrels recede by traveling down vto the lower level 2G of vthe track Vto allow' the cans to fallfrom their engagement with. the heads Qiitlof the upper spindles. When this occurs the cans are carried bythe feedwheel iBS- until delivered into the discharge spout 36, thus completing a cycle of the machines operations.

In uniting the can-shells with both ends, vthe same would be run tliroughthe machine twice, once, for each'of the respective ends and Witli'tlie ends which are being acted uDon upbermost.

From the foregoing it is seen that the ca nf parts, that is, the shells, or bodiesr andan end therefor for each such shell are delivered to and then revolved with the respect-ive pairs of spindles and While so carried the )oints between .such' parts are formed throughthe cooperation of pairs of forming-v Wheels which revolve coincidently with the respective pairs of spindles.

The principal advantage of the invention is the facility withwhich the 'double-seaming of cans is accomplished With a uniform chan acter in the work produced. A'still further advantage isin the low cost of constructing the machine ofthis nature anduin the low cost with which itfcan be operated.
